Outline


  • Mineral-forming processes
    • Melted materials crystallization
      • Magma or lava cools to solids, forming minerals with crystals
      • The faster it cools, the smaller the mineral
    • Materials dissolves into water
      • Water sinks into cracks in ocean's crust, heated, dissolves minerals
      • Rise up out of "chimneys"/vents
      • Solution hits cold water, minerals crystallize, sink to bottom
    • Evaporated water, minerals left behind
      • Mineral-rich water evaporates and leaves solid minerals behind
      • Could be called sedimentary
  • Mineral locations around the world
    • Mostly common rock forming minerals, all spread evenly
    • Rare minerals concentrate in certain areas
